Abstract: 665,729. X - ray apparatus. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. May 2, 1949 [May 29, 1948]. No. 8286/51. Divided out of 665,692. Class 98 (i). An X-ray tube is mounted on one end of an adjusting arm, the other end being pivoted to a support, and a jack-screw is threaded through a nut mounted to swivel on the arm and is held against longitudinal movement with respect to the support while being rotatable to adjust the angularity of the arm with respect to the support. As shown, the support comprises a hollow tube 72 mounted on a carriage (not shown) movable on an X-ray tilt table. An arm 106 carrying the X-ray tube (not shown) is pivoted at 108 to a lug at one end of the.tube 72. A threaded rod 111 is mounted to rotate freely in a bushing pivoted at 117 to a bracket 118 on tube 72, and is turned by a handle 119. This moves along rod 111 a threaded bushing 112 pivoted between extensions 113 of arm 106, which is thus moved to adjust the position of the X-ray tube. Specification 665,692 is referred to.

Title: Method of producing detergent compositions
IPC: C11D3/06
Filed: 1962-03-07
Abstract: Solid detergent compositions are produced by drying a solution or slurry containing an alkali metal tripolyphosphate which also contains 0.05-2%, preferably 0.1-0.5%, by weight of the tripolyphosphate of a compound yielding calcium ions, especially calcium hydroxide or a mixture thereof with calcium sulphate di-hydrate.
